Aqua Ultraviolet Ultima II 4000 Pond Filter, 2" Ports (MPN A50004)

The Ultima II Filters are specifically created to handle high flow rates, extreme loads, and elevated rates. Whether used in an aquaculture facility, backyard pond, or large aquarium system, these filters are essential for maintaining the health of aquatic life in bodies of water ranging from 500 to 60,000 gallons. They effectively remove ammonia and accumulated debris. One of the key features of the Ultima II Filters is the "cyclonic" backwashing system. Equipped with internal jets, this system efficiently cleans the filter in just minutes. The filter also utilizes the Bio-Tube Aqua Media, which is designed in a tubular shape. This design not only protects bacteria but also dislodges unwanted debris. The Ultima II Filters combine both biological and mechanical filtration in a compact body. The design of these filters makes them suitable for high flow rates, extreme fish loads, and elevated feed rates. They are equipped with a "cyclonic" backwash system, which quickly and effectively cleans the filter. In addition, the unique patented tubular bio-media prevents clumping and enhances filtration efficiency. The compact size of the filter body also allows it to be buried, providing a discreet and integrated filtration solution.
